As in other games there are special premium items, I think the company should create more uses for those Bloodstones... I swear I wanted to buy Bloodstones but have around 50 and don't have what to do with them.

It would be pay2win then. All items should be affordable by all players alike.

It's a funny answer because right now the option to refill endurance make the option to lvl up to infinity for the players who can afford it' to refill every day and the other will never get to their levels....
